Craig Bellamy has made two changes to Melbourne Storm's line-up to take on the Gold Coast Titans at AAMI Park on Sunday.

Flying outside back Justin O'Neill returns to the centres to make his first appearance for the 2014 season while Dayne Weston has been named to make his Melbourne Storm debut.

O'Neill will provide the Storm attack plenty of speed and potency after having his start to 2014 delayed through a knee injury. Over the past two seasons, only Billy Slater and Will Chambers have scored more tries than the 23-year old who is sitting on 20 from 2012 and 2013 combined.

After joining Melbourne midway through 2013, Weston will make his Storm debut in Round 5. Weston made the move to Melbourne from Penrith last year after spending two seasons with the Panthers, bringing with him over 60 games of invaluable NRL experience to the Storm playing roster.

The hard running forward played an important role for the club's NSW Cup feeder team Cronulla in 2013, who eventually went on to triumph on Grand Final day.

O'Neill and Weston replace Mahe Fonua and Tim Glasby from Storm's side named on Tuesday.
